(c) Using a feeler gauge, measure the ring end gap.
Standard ring end gap:
N o.1
0.280 – 0.500 mm (0.0110 – 0.0197 in.)
No.2
0.380 – 0.600 mm (0.0150 – 0.0236 in.)
Oil (Side rail)
0.150 – 0.500 mm (0.0059 – 0.0197 in.)

N o.2
1.20 mm (0.0472 in.)
Oil (Side rail)
1.10 mm (0.0433 in.)
If the end gap is greater than maximum, replace the
piston ring. If the end gap is greater than maximum,
even with a new piston ring, rebore all the six cylin–
ders or replace the cylinder block.
3. INSPECT CONNECTING ROD
A. Inspect connecting rod alignment
Using a rod aligner and feeler gauge, check the con–
necting rod alignment.
Check for bend.
Maximum bend:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If bend is greater than maximum, replace the conne–
cting rod assembly.
Check for twist.
Maximum twist:
0.15 mm (0.0059 in.) per 100 mm (3.94 in.)
If twist is greater than maximum, replace the conne–
cting rod assembly.
B. Inspect connecting rod bolts
